//! defines a Texture2Transform node of VRML specifying properties of geometry

|

//! This node defines a 2D transformation applied to texture coordinates.
|

//! This affect the way textures are applied to the surfaces of subsequent
|
|
//! shapes.
|
|
//! Transformation consisits of(in order) a non-uniform scale about an
|
|
//! arbitrary center point, a rotation about that same point, and
|
|
//! a translation. This allows a user to change the size and position of
